Description
Technical field
A kind of electrician trade is changed battery, the slotting pen device of fuse maloperation with the anti-charged pen of surveying instrument
Background technology
Surveying instrument is the measurement instrument that electrician trade is generally used, can measuring voltage, related data such as electric current, resistance, and be the indispensable important measurement apparatus of electrician's operation.When using surveying instrument, need to use the measuring pen that can plug at any time, the related data of reference point, position is measured.
Multimeter in the past though possess above measurement function, can be finished the measurement of related data, but when using, because of being plugged without limits, installs by electroprobe, when changing battery, fuse sometimes, the user for convenience or because not unloading operation is carried out in carelessness when electroprobe is in the measurement state sometimes.If measured target be high-power equipment, very easily take place electric shock accidents, the potential person, life security hidden danger are arranged.
Summary of the invention
The purpose of this utility model is by a kind of measuring pen plug stop means, make and test pencil must be pulled away surveying instrument when the multimeter user changes battery or fuse, and do not finish and change battery, fuse operation, just test pencil can't be inserted in the jack once more, thereby can prevent effectively that the user is because of the issuable potential person of hot line job, life security problem.
The utility model by surveying instrument, movable cover, input protection frame, push limit switch and form, input protection frame jack number is consistent with the set jack quantity of surveying instrument, be 4 holes, 4 holes, one side is provided with co-located, unidimensional interior friendship roundlet, the interior curvature of roundlet of handing over is consistent with surveying instrument test pencil jack curvature, the limit, upper edge is provided with toggle switch, and the place, lower edge is provided with spacing breach; Active face interior surface and input protection frame toggle switch corresponding position are provided with the track stopper slot, and medial surface is spacing dimensional structure with pushing the limit switch place; Push switch is a lever construction, and button is connected with limited block; Surveying instrument body and input protection frame upper edge binding site are provided with the toggle switch breach; Push switch is located at a side of surveying instrument body, and limited block extends to the spacing indentation, there of movable cover by connecting link, with the toggle switch work of staggering the time; Movable cover cover is stuck in surveying instrument body test pencil jack place, and toggle switch is movingly in body toggle switch breach; Movable cover is sleeved on surveying instrument body test pencil jack one end, and track stopper slot cover fits on the toggle switch.
Operation of the present utility model is as follows:
The user must at first dial down test pencil as changing battery or fuse in advance, opens movable cover, battery and the fuse established in just touching.At this moment, toggle switch is in spacing position, hands over roundlet by jack position in the input protection chord position moves to.This moment, limited block leant out from spacing breach, propped up limited block breach one side, and this position limit test pencil can't insert test pencil when not inserting lid activity cover.
Change battery or fuse the operation finish after; movable cover is inserted lid to be resetted; when resetting; the spacing dimensional structure of movable cover at first can be pushed push switch; toggle switch laterally slides into input protection frame jack and multimeter body jack concentric position along the track stopper slot of active face interior surface simultaneously; thereby remove the lockhole state, surveying instrument can continue safe and practical.
The utility model reasonable idea, delicate structure has good operability, and safe effect is good, and promotional value and market outlook are widely arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model, also is the specification digest accompanying drawing; Fig. 2 is movable cover inner face structural representation; Fig. 3 is input protection shelf structure synoptic diagram and installation site synoptic diagram.Each label is respectively (1) body among the figure, (2) movable cover, (3) input protection frame, (4) push switch; (5) limited block, (6) spacing breach, (7) toggle switch, (8) toggle switch breach; (9) hand over roundlet, (10) spacing dimensional structure, (11) stopper slot in.
Embodiment
The utility model is described in further detail now to lift an example.
Embodiment: with VC250 type multimeter is example, input protection frame 3 long 33mm, wide 14mm, big bore dia is 10.14mm, and interior friendship roundlet 9 diameters are 6.64mm, interior friendship roundlet 9 distance of center circle macropore center of circle 3.5mm, middle two macropore centre distance are 19mm, two lateral opening centre distance are 57mm, and toggle switch 7 is apart from push switch 4 one side 37.8mm, spacing breach 6 inset spacing toggle switches 7 centre distance 15mm; Stopper slot 11 groove width 3.2mm, straight flange and axis angle 20 degree, another side arrival line and axis angle 52 degree, through 1.8mm, following folding is for parallel with straight flange, and the flex point place is far from upper edge 25.6mm, and bottom land roundlet center overlaps with center line; Push switch 4 elasticity exceed body construction 0.5mm.
